CERAMIC TECHNICAL DATA SHEET
K-ALOX High Alumina Ceramic Lining Systems K-ALOX has an excellent rating for resistance to all forms of abrasion, with a hardness of 9 MOHS and the ability to withstand very high operating temperatures. K-ALOX also has excellent resistance to corrosion and chemicals.
Manufacture The primary material used for the manufacture of our K-ALOX components is calcined alumina of 92% purity which is a by product of the alumina Industry. In order to achieve its fine molecular structure it is milled and dried achieving a near submicron powder. It can either be pressed or slipcast into alomost any form dependant on size, where it is then fed into a tunnel, shuttle or bell type kiln and subjected to a controlled process of heat treatment reaching temperatures of around 1600째C which results in material with characteristics of extreme abrasion and heat resistance.
Application Key Benefits G
Excellent abrasion resistance
G
Constant operation at elevated temperature
G
Low co-efficient of friction
G
High manufacturing tolerances achieved
The primary use of our K-ALOX material is for the protection of plant against abrasion and erosion when bulk solids or by-products are conveyed or processed by mechanical, pnuematic or hydraulic means. With a hardness rating of 9 on the MOHS harness scale and able to withstand operating temperatures in excess of 1000째C, K-ALOX is ideally suited to counter both impact and sliding abrasion and erosion within the bulk solids handling or processing industries.
Forms of supply Many different forms can be produced in thickness ranging from 1.5mm to 75mm either in the production stage or by cutting and machining the components to fit the geometry of the fabrications they are used to line. The majority of shapes produced are either flat tiles or cylinders, however more complex shapes can be produced by a means of pressing and machining.
Installation The majority of installations are carried out using a range of adhesives with differing characteristics depending on the application. Where adhesives are either not suitable to use or the curing time is not fast enough to support the weight of the component in either a vertical or inverted position then mechanical fixings can be used. Kingfisher can supply a full range of adhesives and mechanical fixings dependant upon the applications. As with most wear resistant materials the success of the systems often depends on the quality and accuracy of the installation. We recommend consultation takes place with one of our qualified engineers in order to assess the suitability of choosing our K-ALOX material for particular applications. If need be Kingfisher can carry out the installation using its own fully trained work force or supervise your own employees.
